Offline-First Mobile (TypeScript, React, Docker backend) overview

A mobile application architected for offline-first operation, where the local database is the source of truth and cloud sync happens opportunistically. TypeScript and React power the cross-platform UI, with an embedded local database storing all user data on-device. A background sync engine reconciles local mutations with the server using conflict-free replicated data types (CRDTs) or last-write-wins strategies. The Docker-hosted backend provides REST APIs for sync, authentication, and push notifications. Zustand manages UI state while the sync engine handles persistence state. The tradeoff is the significant complexity of conflict resolution and the need to test extensively under intermittent connectivity, but the result is an app that works reliably in low-connectivity environments like field operations or developing regions.
